Safir is a computer software for the simulation of the behaviour of building structures subjected to fire. The fire is introduced as a data (in term of a curve giving either the evolution of the gas temperature in the fire compartment or the evolution of the net flux on the surface of the structure) and the Software calculates the evolution of the temperature in the structural elements which can be discretized in 2D or 3D.

The structure is then discretized by means of truss, beam or shell finite elements and the evolution of the structure’s displacements, stresses and strains are calculated. For the mechanical analyses based on 3D beam finite elements, the software can calculate the elastic torsional stiffness of the section.

SAFIR has been developed from the beginning as a tool for modeling the behavior of structures subjected to the fire. The link between the thermal analysis and the structural analysis is thus quite straightforward. It is founded on high performance finite elements, yet it runs on quite ordinary Windows based PC. Its utilization is not complex, provided that the user has a good knowledge of non linear modeling. Training sessions can be organised at a reasonable prize (650 euros per day, excluding VAT).
